The available dialysis modalities are haemodialysis (HD),
continuous renal replacement therapy (CRRT), sustained low-efficiency dialysis (SLED) or peritoneal dialysis (PD). The choice depends on a number of circumstances, including which therapies are on offer at the patient’s hospital,
their haemodynamic state, present co-morbid conditions, and the physicians preference. It is important to recognize that not all patients will choose to receive RRT. This must be assessed on a case-by-case basis, and the ramifications of
not receiving this treatment must be thoroughly explained to both patient and family. Patients
with sepsis or hepatic failure may see possible benefits with continuous therapies. In spite of the overall safety of these
dialysis modalities, complications and adverse problems can occur. This requires detailed attention, and in some instances, frequent laboratory measurements to anticipate and avoid their incidence
